Description

Technical Field

[0001] The present application relates to the technical field of composite modified asphalt processing, and specifically discloses a composite modified asphalt modifier feeding device. Background Art

[0002] Asphalt modifiers refer to natural or synthetic organic or inorganic materials added to asphalt or asphalt mixtures, which can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt.

[0003] Desulfurized rubber powder is a specially treated material with good adaptability and a wide range of applications. In emulsified asphalt, desulfurized rubber powder can improve the performance of emulsified asphalt. By adding a certain proportion of desulfurized rubber powder, the physical properties of emulsified asphalt can be improved. The dosage of modifier has a huge impact on the performance of modified asphalt. Studies have shown that when using 100-mesh desulfurized rubber powder with an activation degree of about 50% to prepare emulsified asphalt, the dosage of desulfurized rubber powder can be greatly increased to improve the performance of emulsified asphalt.

[0004] When producing composite modified asphalt, desulfurized rubber powder, used as a modifier, needs to be added to the modified asphalt production equipment and mixed with the asphalt content in a strictly pre-mixed ratio. However, existing modifiers are granular. Directly adding them to the modified asphalt production equipment prevents them from fully blending with the asphalt, affecting the production performance of the composite modified asphalt, resulting in waste of both the modifier and the asphalt, and reducing the production efficiency of the composite modified asphalt. Therefore, the inventors have developed a composite modified asphalt modifier feeding device to address this issue. Utility Model Content
